Transaero decided to move both 2x daily flights to LHR from Moscow Domodedovo to Moscow Vnukovo (they moved one rotation already and now announced to move second rotation).
I see "easyJet" is not placing on sale LGW-DME route, but they managed to put MAN-DME fast after announcement.
AFAIK, "easyJet" get permission to operate LON-MOW flights with condition they are going to have codeshare with Transaero (it should be a first easyJet codeshare route and very rare in LCC world).
My doubt is, maybe "easyJet" having problems in managing codeshare with Transaero? Maybe that is the reason of the delay with the start of sales?
